Abstract
A method of treatment of a tumor comprising the steps of catheterization of the arterial vessel that feeds the tumor, and transcatheter administration of a suspension of magnetically hard ferromagnetic material in an oil solution of an oil-soluble antitumor substance with simultaneous application of local magnetic field onto the area of the tumor. After 1-3 days the tumor is subjected to ultrahigh radio frequency electromagnetic field or ultrasonic waves to produce heating of the tumor tissue to the temperature of 43.0.degree.-43.5.degree. C. for a period of 5-45 minutes.
Claims32
A method of treatment of a tumor comprising:
- (a) catheterization of a blood vessel that supplies the tumor;
- (b) provision of a ferrochemoembolizing composition consisting of a magnetically hard, radio-opaque ferromagnetic material suspended in an oil solution of an oil-soluble antitumor substance;
- (c) application of a constant magnetic field onto a tumor area;
- (d) injection of said ferrochemoembolizing composition through said catheter, thus providing the formation, within the tumor vascular network, of a stable, compact, porous ferromagnetic aggregate harboring said oil solution of said oil-soluble antitumor substance;
- and,
- (e) subsequent heating of the tumor by application of an oscillating power field to the tumor-bearing area, under the conditions that selectively produce necrosis of the tumor tissue.
